Chanonry.—Practically blank as regards actual migration, all movements being local, Mr. J. McGill finding Scarts and Cormorants flying up and down the Firth, Wild Ducks feeding in frosty weather, and many Larks on Jan. 17th, 1884. Local movements of Green Plover in November and December. No certain migration discernible.
Kinnaird Head returns a blank schedule, with the positive statement "No birds." I am obliged to the head lighthouse-keeper for returning this schedule. Such if regularly returned would enable me to give always, year by year, a positive statement of negative value. I wish others on the Aberdeenshire coast would follow his good example.
Girdleness.—A light return during November 14th to 17th and December 1st to 12th. "Birds at this lighthouse very scarce, the situation being very exposed." A record of a Fork-tailed Petrel (seen by me on 15th August, J. A. H. B.) is of considerable interest. Dead calm and hazy; on E. side of lantern; about 12 p.m. Stomach contained only an oily matter (Geo. Sim) vide Proc. Ryl. Phyl. Soc. Edin. 1884. Bell Rock sends excellent schedules as usual. The early advent of a swallow—March 13th and 14th—is commented upon by letter. "It seemed much exhausted." Mr. Hutton, Bank Manager, Royal Bank, Arbroath—a gentleman much interested in ornithology—gave a full account of the occurrence in the 'Dundee Advertiser' of April.[8]
[8] "About four o'clock in the afternoon of the 13th and 14th March the light-keeper on duty at the Bell Rock Lighthouse observed a swallow fluttering in front of the kitchen window. After watching it for some little time he opened the window and stood aside to see if the bird would come in. This in a minute or two it did, and alighted on the inside of the windowsill. So exhausted did the little wanderer appear from its long flight and the buffetting of the weather that it allowed itself to be lifted up and put into a cage. It immediately lay down on the bottom of the cage and instantly fell fast asleep, remaining in this state till next morning about eight o'clock (sixteen hours). So sound were its slumbers that the keepers watching it as it lay could scarcely detect any signs of life in it, and at times they were almost certain that it had died. On awakening at the hour mentioned the swallow was taken out by one of the keepers and given a drink of water. It was put back into the cage again, where it lay in an apparently dormant condition till 10 A.M., when it was supplied with more water, under the influence of which and the rays of the sun it became quite lively and strong. The kitchen window was now lifted up and the bird taken out and laid on the open hand of Mr. Jack, principal light-keeper. Resting there for a moment, it gave one cheery twitter, and, springing upwards from the outstretched palm, it winged its way in the direction of the land and was lost sight of in the space of a minute or two. The appearance of the bird so far north at such an early season is remarkable. The swallow migrates to Africa at the end of October, and it is not till the middle of April that the flight northward begins, so that the one which surprised the light-keepers before March was half run was several weeks earlier than the usual time for their appearance here. It may be added that, the Swallow being an insectivorous bird, the lighthouse keepers were unable to supply it with its ordinary food, and abstained from giving it any other for fear of injuring it."
Between April 9th and Sept. 3rd scarcely any migration was observed at Bell Rock—only four records in that time on April 28th, April 30th, May 7th and 9th. But before and after these dates in spring and autumn, considerable migration is recorded in comparison, but decidedly slack, as compared with other seasons, in autumn, owing to northerly and westerly winds. This, however, was followed by a great rush in November, for particulars of which the reader is referred to the details under Species. The marvellous congregations of Gulls and their prey the Sprat or Garvie (Clupea sprattus) are commented upon. ([General Remarks]).
Isle of May.—In January, 1884, intermittent migration continued. The great gale of 27th to 29th produced nothing of any consequence—one Yellowhammer, however, being the first of the species seen for some time.
While rushes took place in spring at Bell Rock in March, with the wind prevailing E., at Isle of May much smaller movements are recorded, local winds apparently being more S. & W. (See especially "Thrushes," but the remark applies to other species also.) This is curious at two stations so close to one another. Bush of land birds in April. Movements of Guillemots and rock birds somewhat different (see details). Partial albino of the Willow Warbler captured (seen by me, J. A. H. B.) Long spell of E. winds in April and rushes; but a light S.W. wind on 30th, changing from S.S.E., brought a "wonderful rush of land birds." This seems to me interesting, as proving the station to lie in the direct route of migration, rushes occurring both in the most favourable winds—S.E. or E. (i.e. for spring migration), and those supposed to lie less favourable, and following winds, viz. S.W.
A later schedule—April 30th to June 3rd—shows evidences of a decidedly late spring migration, for which it seems difficult to assign a cause. This was also noticeable on land. It took place in second week of May, with light S.W. and W. wind, mist, fog, and rain; principally of Warblers and insect-feeding species.
Very few records are given between June 11th and August. A usual return of Warblers, &c., noted as rather early by August 10th. Bush of same species, 19th and 24th. In end of August and all September, on till about October 18th, winds retarded migration, being N. and W.; never, or very rarely, S. and E., or S. of W. I spent three weeks and three days on Isle of May, between September 24th and October 17th, and during that time only witnessed intermittent and slack migration; the only attempt at a night rush apparent being on the night of October 4th, at the time of total eclipse of the moon—wind Light W. at the time—some twelve Goldcrests being caught at the lantern.[9] A male Black Redstart was shot on October 24th, and a second seen on 25th. The principal rush of the year on November 4th instances the effect of a sudden change of wind. This must have been a very vast and determined rush, as many came also with a W. wind afterwards. This rush was composed principally of Finches and Larks, with considerable numbers of Turdidæ; but the great rush of the latter (Thrushes) did not take place till the rush of the Finches was past. Whilst the Finches and Larks greatest rush was on Nov. 4th, the greatest rush of Thrushes, Blackbirds, and Turdidæ generally was on 12th to 16th. (For particulars see details under Species).
